About

Imagine having complete, real-time visibility into your cryptocurrency inflows without ever sacrificing security or control over your assets. That is precisely what PayzCore delivers. We understand that in the world of digital commerce, especially when dealing with stablecoins like USDT and USDC, knowing instantly when a payment arrives is mission critical, but handing over custody of your private keys is absolutely non-negotiable. PayzCore solves this dilemma by acting as your dedicated, non-custodial blockchain monitoring service. You simply provide us with your watch-only extended public keys (xPubs), and our robust API takes over the heavy lifting. We diligently scan your derived wallet addresses across five major blockchain networks, instantly detecting any incoming USDT or USDC transfers. The moment a transaction is confirmed, we push a real-time webhook notification directly to your system. This means your accounting, order fulfillment, or internal processes can react immediately, all while your funds remain securely locked in your own wallets. It’s like having a tireless, digital auditor watching your crypto accounts 24/7, ensuring you never miss a beat or wait for manual reconciliation again.
